ABSTRACT:
An apparatus for analysis of samples containing organic matter, especially of rock from oil drilling mud, including a loading arm hinged at its base to be movable from a tilted position when it receives a sample-bearing cartridge, which fits on the top of the arm, to a vertical position in which the arm can be raised to fit the upper end of the cartridge within a selectively electrically heated and air cooled chamber. A channel for carrier gas, e.g. hydrogen, passes up the arm so that gas passes through the cartridge when it is held in the heating and cooling chamber, and through the heating and cooling chamber and then through a conduit to a burner within an ignition an analysis chamber.
In use, the container is heated to pyrolyze the sample and the resultant vapors are entrained in the gas, burnt and analyzed by flame ionization. After which the sample-bearing cartridge is cooled in the heating and cooling chamber.
